Replacement Soft Strap Heart Rate Monitor, S to XL Size. Model BBHRS1

I am a professional and wear this strap every day. The performance is excellent for a few weeks and in so doing, it does it job well. I do, however, I replace this strap with a new one when the impedance increases from 2,000 ohms to about 20,0000 ohms. [The impedance will actually increase to the meg-ohm range in the extreme and then the strap output is a function of electrical charge not power transfer. ] I have not determined how long the change from 2,000 to 20,000 ohms takes, perhaps 4-6 weeks depending on how the strap is used. I have not determined what breaks down the conductive components in the strap. I keep on buying more straps and I am very glad to have the straps. It is the only strap from Amazon for me. [made in China]. There is another lower impedance model strap from another country but it is not yet available from Amazon.David W. Young

I brought this an a replacement for my Zephyr hxm strap, and it worked without issue, but it still as easy "wrap" as the original which make wearing it a bit uncomfortable.

This strap is far better than the one that came with the Zephyr HXM. I waited until I used it a bit before writing this review because I wanted to see how it held up with lots of heat and sweat. It easily outperforms the Zephyr strap that comes with this:http://www.amazon.com/Zephyr-Bluetooth-Wireless-Android-Windows/dp/B002PL33AQThe stock strap is uncomfortable and it bunches up/curls up when it gets wet.Oh, and the Zephyr replacement strap? $30 with shipping. Insanely overpriced. Their HXM works perfectly, but I would never buy from them again.

Well, I bought this, thinking it would solve my problem. The Heart Rate Monitor stops working when you get sweaty and the reviews on this sounded like it would solve the problem, but nope... I'm back to wearing my Garmin HRM.

Very comfortable and seems more durable than the strap that shipped with the heartrate monitor. I do wear the strap almost every day for an hour, but the original one wore out very quickly. When I say it wore out, I mean that the pads became unattached from the strap. It worked that way for awhile (pads halfway attached) but eventually it no longer transmitted my heartbeat. I've had this replacement strap for a few months and there is no sign of wear so far.

After I lost my strap for my heart monitor I was on the search for another. Out of all my searching, this strap was the cheapest. I don't have BLU brand heart rate monitor either so this works for other brands as well. I snapped my heart rate monitor on it and it worked as great as the original. Shipping was good also.

I've been looking for a replacement for my original Zephyr monitor strap and decided to give this a shot. I tried it for the first time yesterday and it works great. It also doesn't require adding water before starting the workout (as the original Zephyr strap did).

I've gone on several runs with this strap using my Zephyr HxM BT HR Sensor and it's worked great. I highly recommend.
